I was watching a video on you tube and the guy on this bike did a velodrome time trial with a top speed of 41 m/hr. That's nearly 66km/hr. One fast bike. The owner who is selling it said it is faster than his Velokraft VK2 with a tail box. The price is is USD$3500 + USD$800 postage + GST and UPS custom clearance fee. Probably work out about Aus$5100 - $5500.

If I were to spend that much money what other low racer bike could you think of. M5 Tica??

Here is another video. This was the first time that I had ever been on a velodrome track and it was just a little scary. Actually.....I was hanging on with all I had around those turns. Now I'm more use to the track and it's no big deal. It's all good now. http://www.youtube.com/watch?v=Wq3NybmF ... re=related Cheers again......Bob

With the equivalent width and PSI, smaller diameter wheels are fast. There is a small theoretical difference.No stability loss. They are quicker than larger for changing direction. Smaller wheels give me a harsher ride over rougher road surfaces, but it could be to do with the 120PSI I am running.

I run Pro race 3's and 110psi rear, 90psi front on 650c wheels. These have been the most comfortable tyres for me but still feel harsh on less than good asphalt. Lowering the pressure helps but risky with pinch flats. I've also experimented with the max pressures (115) for speed values but that was horribly rough going. It made my teeth chatter so bad and trying to talk to others sounded awful, like chipmunks. it didn't appear to be any faster either.There is also a large proportion of European manufacturers that are sticking to the 20 inch format with most of their bikes.Ian Simms from Greenspeed also mentioned that the same profile of a tire, with the same air pressure, has less rolling resistance when smaller.In all of this though I haven't seen any high pressure 20 inch by 23mm wide tyres. I can imagine they would make a harsh ride.

Inflating tyres to about 90% of maximum will give a better ride and faster speed over rough chipseal type road surfaces.My 28mm/406(20 inch) should not be run under 65psi.I have not seen any 23mm tyres.

The smaller diameter wheels also have greater acceleration. On rough surfaces max pressure can be counter productive not to mention loss of traction and its inherent danger. Another problem is the waste of power bouncing around. There was an article I recall somewhere with particular reference to bents. If I recall it suggested fatter tyres could be faster. Have to see if I can find it again.

Looking at the NME it seems very limited in turning ability due to the chain line. I cant see it being great on road and guess it is all about racing. Love to see it in the flesh. Seems similar in layout to the NoCom. My big concern would be that in some of this style lowracer there is hard overlap of the cranks with the wheel or so it sees in pictures. Never actually seen any lowracer except my own LWB one.

John, For me,the NME & the Nocom are not for in town riding. Oh,I'm sure a rider could do it & I'm sure people do it all the time.....but not for me. I want the open road. I have a ten mile stretch of flat road I train on out in the boon-docks,away from cars. As anyone knows, these lowracers are not known for their great turning ability......but that's not what I want them for....What I want is SPEED!...pure & simple. For anything else I ride my Windcheetah(also fast). Bob

Thanks Bob, I'm going to have to find someone with a "real" as opposed to my homebrew LWB, lowracer and have a look up close. Easier said than done here hence my questions. I agree I don't think they are meant for round town . I would like to go fast though.

I commute on my Home brew FWD dual 406 dual chain lowracer. I can do a slow 2 lane Uturn. Tighter without pedaling. I Imagine the NME with no chain management wouldn't do as well. If it bothered someone they could always add an idler. I think a bigger problem with these was the one sided fork flexing.
